Can you check for any differences betwewn the newly created VM and the old one. Set an alias as follows: alias virsh='virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf' Then: virsh dumpxml oldVM virsh dumpxml newVM Maybe somethhing can give a clue what is going on.

Maybe it's related to the CentOS 5.2 e1000 kernel module . Can you install another CentOS 5.2 and verify that the issue exists? Any chance to upgrade the VM to 5.11 or just update the kernel so it is at least 2.6.25 , so you can try the virtio NIC ? Best Regards, Strahil NikolovOn Jan 12,

I guess I didn't clarify myself. I asked if you can shutdown the VM and then set only this VM's 'Custom compatibility mode' to 4.2 and power up to test. Yet, if the cluster was at 4.2 when you imported , then I am afraid that the 'Custom Compatibility mode' won't make a difference. I'd

Hi Latcho, Most probably it's a bug. Have you tried virtio and/or rtl-based NIC ? As far as I know, CentOS 5 supports Virtio after Kernel >= 2.6.25 . Best Regards, Strahil NikolovOn Jan 11, 2020 19:54, Latchezar Filtchev wrote: > > Hello Everyone, > >   > > I am aware my guest OS is out of
